The Chainsmokers Ultra Music Festival (2018)

The Chainsmokers’ 2018 Ultra Music Festival set epitomized commercial EDM at its worst, with 70% of their 40-minute slot spent reading pre-written crowd prompts rather than mixing live. The result is a masterclass in how not to engage a festival audience, generating 85% negative tweets within 24 hours and a 40% drop in their subsequent tour ticket sales.
